3D Scanning, Reverse Engineering, and Data Capture

3D Scanning

3D Scanning can be used to create a digital 3D representation of an existing physical object at an accuracy of ~50-100 microns. The digital models can be used for graphic visualization, reverse engineering, replication, and designing surrounding parts or assemblies.

Output

Our standard deliverable is an STL mesh file. STL files represent an object's surface using a collection of interconnected triangles and are commonly used for visualization, inspection, and 3D printing workflows. If you desire a Parametric model derived from the scan data, we can assist with this procedure as well (at additional cost).  Examples of parametric model formats include Solidworks, Autodesk Inventor, or STEP file formats.

Tech Foundry Hardware

Tech Foundry is armed with an assortment of different types of 3D scanners (handheld, and bench-top).  We are able to capture data in-lab, or on-site.

Keyence VR-6000 Wide-Area Optical Profilometer

 

• Type: Benchtop optical profilometer
• Scan Area: 100 × 72 mm (single shot); expandable via stitching
• Resolution: 0.1 µm (height), 1 µm (X-Y)
• Scan Speed: Full surface capture in as little as 1 second

Units: 1

Location(s): Aggie Square (Sacramento)

Pros:

• Captures full surface data in as little as 1 second
• Measures glossy, matte, and reflective surfaces without spray coating
• Motorized rotation captures recessed features and undercuts
• Extremely high resolution for fine surface detail

Cons:

• Benchtop only — objects must be brought to the scanner
• Limited to small objects that fit on the measurement stage
• Outputs surface profile data, not a full 3D mesh like other scanners
• Not suited for large or irregularly shaped objects

Example Scan Data

Scanner Compatibility

Generally, our 3D scanners work by emitting structured light (visible, or non-visible) and studying the reflected light that bounces back.  As such, objects are ideally opaque, with no hidden/interior features in order to capture a clean-scan.  In instances where your object is translucent or reflective, we ca n apply a temporary spray coating (which evaporates off after a few hours) to make your part compatible with our process.  

Ideal Scale

Ideal objects for 3D scanning range from a minimum of a few centimeters in length to a maximum size roughly equivalent to an automobile.

Reverse Engineering

Often related to, or incorporating elements of 3D scanning, our reverse engineering service utilizes skilled engineers to develop parametric models from existing physical parts. This process is particularly valuable when replacement parts are no longer commercially available or when new designs must be derived from or replace existing objects. We provide accurate digital models to support redesign, modification, or replication efforts.

Note

• With decades of engineering design expertise, we approach reverse-engineered models with the same mindset as the original engineer, ensuring that our models faithfully reflect the original design intent

Data Capture: Motion Capture & Gait Analysis

Tech Foundry is equipped to perform motion capture and gait analysis. We recommend using iPi Soft Motion Capture software with two Microsoft Kinect 2 sensors, which can be enhanced by adding additional cameras for improved capabilities.

Tech Foundry Hardware and Software

Our motion-capture system uses two Microsoft Kinect2 sensors, webcams, and scene reconstruction/analysis software. These tools primarily capture an object’s geometry or analyze gait and movement. The Kinect2 sensors employ an array of technologies, including time-of-flight sensors and cameras, to gather data.

Rates

• Note: We strongly recommend submitting a service request to obtain an accurate project cost estimate. Self-quoting can often lead to miscalculations

Our development services come with a simple per-hour rate defined in the chart below.  We assess a 1 hour minimum, then to the nearest quarter hour.  If your process involves use of our 3D scanning technologies, we also access an hourly fee for use.

*Student development time may not be available, or applicable to all projects. Tech Foundry will leverage it where possible.

Estimating project cost should be left to Tech Foundry, but here are some general project estimates that can guide in self-estimating:

*All declared values at internal rates, NUD = university required "Non-University Differential" added for external.
